NORMAN D. CROSS, OF SILVER- CREEK, NEW YORK.

W0 ODWORKING-MACHINE Specification of Letters Patent.

Patented Jan. 5, 1909.

Application filed June 5, 1908. Serial No. 436,956.

To all whom it may concern:

Be it known that I, NORMAN D. CRoss, a citizen of the United States, residing at Silver Creek, in the county of Chautauqua and State of New York, have invented a new and useful \Voodworking-Machine, of which the following is a specification.

This invention relates to wood working machines, and more especially to that type of wood working machines designed to size and slit fan handles.

One object of the invention is to provide an improved and automatic means for sizing and slitting fan handles and the like.

Another object of the invention is to provide an improved means for holding said fan handles, and the like, while undergoing the sizing and slitting operation.

The invention in general comprises a rotatable device for holding a fan handle, a saw for cutting the same to the proper length, and a saw for slitting the same.

The invention further consists in certain novel arrangements of details and combinations of parts hereinafter fully described, illustrated in the accompanying drawings, and specifically set forth in the claims.

In the accompanying drawings, like characters of reference indicate like parts in the several views, and Figure 1 is a side elevation of a machine constructed in accordance with the present invention. Fig. 2 is an end elevation of such machine. Fig. 3 is a top plan view thereof. Fig. 4: is a detail view of the mechanism connected with the holding device.

The base of this device comprises a set of legs, as indicated by 10, with suitable cross and brace bars. Upon the legs 10 is mounted a table 11. Upon the table 11 are rigidly mounted a pair of legs 12 supporting a receptacle 13 for the handles before they have been sized and slit.

Mounted adjacent one end of the receptacle 13 is a chute 1 1 provided with suitable guides 15 arranged so that one end of the handles may be alined vertically therein. Beneath the chute 14 and radially ali ed therewith is a revolving disk 16 provided with a plurality of slots as indicated'at 17. The disk 16 is fixed upon a spindle 18 whereon is mounted a cam 19 fixed against rotation with the spindle. A plurality of pivots 20 are provided on the disk 16, one of said pivots being adjacent each of the slots 17. Upon the pivots 20 are mounted levers 21 having each a downwardly extending finger 22 arranged to lie within one of the slots 17. Each lever 21 has an inwardly extending arm 23. The inner end of the arm 23 lies close to the cam 19 and is in the path of the outer portion thereof. Springs 25 normally hold said levers in such position that the fingers will be pressed away from the opposite side of the slot to that on which the levers are mounted. The cam 19 is provided with an active face 26 which is engaged by the inwardly extending ends of the levers as the disk rotates and serves to force the fingers 22 across the slots 17, as shown in Fig. at. As the bottom of the guide 15 is in radial aline ment with the disk 16, it is obvious that when one of the slots passes the bottom of the guide, a fan handle will drop from the guide into said slot.

It is to be observed that the cam 19 is so positioned on the spindle 18 that the active face 26 comes in contact with the portion 2 1 of the lever 21 immediately after the unfinished fan handle has dropped within one of the slots 17. This causes the finger 22 on the lever 21 to grip the fan handle between itself and the operative side of the slot, thus holding the same firmly and in readiness to be operated upon. The table 11 is provided with a slot 27 about opposite the position of the guide 14. The active face 26 of the cam is so arranged that when the different levers have reached a position adjacent the slot 27, they are released and the springs 25 act to restore the levers to the initial receiving position so that the work is free to drop through the slot 27 into any convenient receptacle that may be placed below the slot 27. Mounted upon the frame 10 in bearings 28 is a shaft 29 carrying a belt pulley 30. The shaft 29 extends above the table and carries a saw 31 of proper thickness for slitting the fan. A beveled gear 31 is fixedly attached to the shaft 29. Upon the spindle 18 is mounted a bevel gear 32. Held in suitable bearings on the frame 10 is a shaft 33 extending substantially from the spindle 18 tothe shaft 29. Upon the shaft 33 are bevel gears 34 and 35 which intermesh with the gears 31' 32. These gears are so proportioned to each other that when the saw 31 is rapidly rotated at the proper speed for cut ting, the spindle 18 will also be rotated against the action of the saw at a suitable speed for carrying the handles to and against the action of the saw. Mounted on the frame 10 is a vertical shaft 36 carried in suitable bearings not deemed necessary here to be shown. Upon this frame is also mounted a shaft 37 likewise carried in bearings of ordinary character. Suitable bevel gears, as indicated at 38, serve to connect the shaft 36 and 37 with the shaft 29. Held in bearings carried on the underside of the table 11 is a shaft 39 upon one end of which is mounted a bevel gear 40 meshing with one of the bevel gears 38 on the shaft 36. Upon the opposite end of the shaft 39 of the bevel gear 40 is carried a trimming saw 41 which projects a short distance above the top of the table and lies: in the path of the fan handles as they are carried around by the disk 16.

From an inspection of Fig. 3, it will be observed that the saw 41 is in such position as to first come in contact with the fan handle asit is carried around by the disk 16 and the saw 31 acts upon the fan handle after the saw 41.

As previously described, the fan handle carried in the guide 14 drops down into one of the slots 17 and is there gripped by the lever 21. The fan handle is then carried forward and comes in contact with the saw 41 where it is cut off to the proper size. It then is carried further around and comes in contact with the saw 31 and as the saw 31 is arranged to lie in the immediate plane of the fan handle as it is carried around, the saw 31 slits the fan handle. From this point the handle is carried around to the slot 27 and is dropped into the receptacle as previously set forth.

For the purpose of disconnecting the feeding disk and starting the same, there is provided a lever 42 whereon is mounted a hearing for one end of the shaft 33. The lever 42 has a handle 43 so that it may be raised at any time and thus disengage the gear 35 from the gear 32. There is thus provided a means by which the motion of the disk 16 may be stopped without affecting the motion of the saws 31 and 41.

For the purpose of properly holding the cam the disk shaft is provided with a recess as shown at 44 and a reduced end of the cam shaft fits therein so that the disk shaft may revolve without revolving the cam shaft. To prevent revolution of the cam shaft a brace 45 is provided which is securely attached to both table and cam shaft.

What is claimed is:

1. In a wood working machine, a spindle, a revoluble feeding disk carried by said spindle and provided with a plurality of radially disposed slots, levers pivoted to the I disk and provided with gripping fingers exduring the rotative movement of the disk, a

feed guide open at the bottom and under which the slots are successively presented to receive the successively lowermost articles from the guide, a trimming saw arranged to cut away portions of the articles of ex,- cessive length, and a slitting saw disposed at a right angle to the trimming saw and arranged to engage and slit the articles as they pass said saw.

2. In a wood working machine, a rotatable feed disk provided with a plurality of radial slots, a work chute having a bottom discharge with which the slots are arranged to successively register to permit the passage of the successively lowermost articles from the work chute into said slots, levers pivoted to the disk and provided with work clamping fingers entering the slots, a stationary cam with which the inner ends of said levers engage to effect clamping of the work, springs tending to move said levers to re lease position, and a pair of saws disposed in planes at a right angle to each other, and in the path of movement of the articles carried by the feeding disk.

3. In a wood working machine, a table provided with a discharge slot, a vertical shaft extendingthrough the table, a feeding disk carried by the upper portion of the shaft and provided with a plurality of radially disposed work receiving slots, a feed chute having a bottom discharge and under which the slots are successively passed to receive the successively lowermost articles from the chute, levers pivotally mounted upon the disk and provided. with work gripping fingers extending into the slots, the upper end of said shaft being provided with a central recess, a cam shaft having its lower end fitting within said recess, a rigid bracket fixed to the upper end of the cam shaft, a cam supported by. the shaft and arranged in the path of movement of the inner face of the levers and trimming and slitting saws disposed in the path of movement of the articles carried by the feeding disk.

In testimony that I claim the foregoing as my own, I have hereto aflixedmy signature in the presence of two witnesses.
